Geography: We will do exploration of how features on the earth’s surface can appear differently using different map projections. To do this, visit Penn State University’s gallery of map projections here: http://projections.mgis.psu.edu
- Spend some time exploring the different map projections available by choosing different projections under the “Choose a Map Projection” pull-down menu. For a visual representation of the distortion in each projection, click on “View/hide distortion ellipses,” then “Redraw the Map.”
Questions. Once you have viewed the different projections, choose three projections to compare and contrast. Answer the following questions for each projection. (2 points each; 6 points total)
- Projection name (0 points)
1.

3.
- What is the developable surface? (0.5 point)
- What type of projection is it (conformal, equidistant, et cetera)? (0.5 point)

- What portions of the earth’s surface are preserved? (Use the distortion indicatrices [from Tissot’s indicatrix] to answer this question.) (1 point) link: https://blogs.esri.com/esri/arcgis/2011/03/24/tissot-s-indicatrix-helps-illustrate-map-projection-distortion/
